Model-based Segmentation and Deep Learning for Lung Cancer

Lung cancer is one of the life taking disease and causes more deaths worldwide. Early detection and treatment is necessary to save life. It is very difficult for doctors to interpret and identify diseases using imaging modalities alone. Therefore computer aided diagnosis can assist doctors for the early detection of cancer very accurately. In the proposed work, optimized deformable models and deep learning techniques are applied for the detection and classification of lung cancer. This method involves pre-processing, lung lobe segmentation, lung cancer segmentation, Data augmentation and lung cancer classification. The median filtering is considered for pre-processing and the Bayesian fuzzy clustering is applied for segmenting the lung lobes. The lung cancer segmentation is carried out using Water Cycle Sea Lion Optimization (WSLnO) based deformable model. The data augmentation process is used to augment the size of segmented region in order to perform better classification. The lung cancer classification is done effectively using Shepard Convolutional Neural Network (ShCNN), which is trained by WSLnO algorithm. The proposed WSLnO algorithm is designed by incorporating Water cycle algorithm (WCA) and Sea Lion Optimization (SLnO) algorithm. The performance of the proposed technique is analyzed with various performance metrics and attained the better results in terms of accuracy, sensitivity, specificity and average segmentation accuracy of 0.9303, 0.9123, 0.9133 and 0.9091 respectively

Feedback Artificial Shuffled Shepherd Optimization-Based Deep Maxout Network for Human Emotion Recognition Using EEG Signals

Emotion recognition is very important for the humans in order to enhance the self-awareness and react correctly to the actions around them. Based on the complication and series of emotions, EEG-enabled emotion recognition is still a difficult issue. Hence, an effective human recognition approach is designed using the proposed feedback artificial shuffled shepherd optimization- (FASSO-) based deep maxout network (DMN) for recognizing emotions using EEG signals. The proposed technique incorporates feedback artificial tree (FAT) algorithm and shuffled shepherd optimization algorithm (SSOA). Here, median filter is used for preprocessing to remove the noise present in the EEG signals. The features, like DWT, spectral flatness, logarithmic band power, fluctuation index, spectral decrease, spectral roll-off, and relative energy, are extracted to perform further processing. Based on the data augmented results, emotion recognition can be accomplished using the DMN, where the training process of the DMN is performed using the proposed FASSO method. Furthermore, the experimental results and performance analysis of the proposed algorithm provide efficient performance with respect to accuracy, specificity, and sensitivity with the maximal values of 0.889, 0.89, and 0.886, respectively.</jats:p
